residuals.uRegress: Extract Residuals from 'uRegress' objects

In statdivlab/rigr: Regression, Inference, and General Data Analysis Tools in R

Extract Residuals from uRegress objects

Description

Extracts residuals (unstandardized, standardized, studentized, or jackknife) from uRegress objects.

Usage

## S3 method for class 'uRegress'
residuals(object, type = "", ...)

Arguments

object	an object of class uRegress, as returned by regress.
type	denotes the type of residuals to return. Default value is "", which returns unstandardized residuals. "standardized", "studentized", and "jackknife" return the expected type of residuals.
...	other arguments

Details

Relies on functionality from the stats package to return residuals from the uRegress object. "studentized" residuals are computed as internally studentized residuals, while "jackknife" computes the externally studentized residuals.

Value

Returns the type of residuals requested.

Examples

# Reading in a dataset
data(mri)

# Create a uRegress object, regressing ldl on age
ldlReg <- regress("mean", age~ldl, data=mri)

# Get the studentized residuals
residuals(ldlReg, "studentized")

# Get the jackknifed residuals
residuals(ldlReg, "jackknife")
